We could not seem to get seeds to germinate no matter what process we used. Had 3 live plants shipped. All 3 planted in differing light areas and soils to improve our chances of at least 1 surviving. All 3 had one frond slowly turn brown and wilt off to main stem. One I split root ball up 4 ways, one just 2 ways, last not at all. One in shade, one in direct sunlight, one mixed. Daily temps first week in 70- and low 80s. Second week 95 was high and 68 low for a few days, lots of rain. Is there anything we can do to ensure 1 survives? (we also have a professional 40 X 20 greenhouse on the lot with lots of windows and ceiling with skylights.) What are we doing wrong or can we do better to help them? (also gave 2 of 3 Superthrive Organic Plant Food mixed as directed.)
